Problem with only receiving intermittent notification of SMS messages, even from the same mobile


It is probably not your phone but your carrier. Contact them and complain!!

Sometime updating the "roaming feature" will help.

Here is the info for Verizon, but many other carriers are similar:

Hope this helps. J

Updating Preferred Roaming List(PRL)


Verizon Wireless is constantly advancing its roaming technology to provide you with superior roaming capabilities. By updating your PRL every few weeks, you can be sure you have access to our enhancements. As a result you may experience:
  • Longer battery life
  • Fewer dropped or blocked calls
  • Clear, crisp connections in more areas across the United States
  • Ability to connect to the digital network in more parts of the country

Instructions for updating your PRL:

  1. Power on your phone within any Verizon Wireless digital service area.
  2. Dial *228 and then press SEND (this call is airtime free).
  3. When prompted, press option 2 to update your phone's roaming capabilities
    (the update may take up to 2 minutes).
  4. Once completed, a confirmation message will appear to inform you that your phone has been re-programmed with the new PRL.

To find the Mobile Equipment Identifier (MEID) on your device, following the steps below:
  1. From the Home screen, touch Applications app_icon.gif > Settings > About phone > Status.
  2. The MEID is provided in two formats:
    • Dec: Decimal number

I have a question to ask


It does sound like a provider issue. I've used Straight Talk before and I like them except when their system has a hiccup, you call and sit on the customer service line for a while; but 9 out of 10 times they just had me enter the " update roaming code" (*22890 *22800 *22801 and *73) for me it was the *22890 - REMEMBER TO REBOOT (TURN YOUR PHONE COMPLETELY OFF, THEN BACK ON ). I would try this first and if this does not work call straight talk. If it does work, write down the code that works and keep it close, cause if your phone acts up (and it will) enter the code!

How do i recover the dec number cause the sticker is off for w385


*#06# may or may not work. The feature was not added to all Motorola phones until after the w385 was in production. You can also find a website that will convert the MEID into a DEC number. The ESN is not a DEC if it has letters. DEC is only numbers and should start with 26. MEID and ESN or HEX have a mix of letters and numbers. There are converter websites if you find the MEID to convert into DEC. Motorola has one too. I'll find it.

Isamsung glyde phone locked in nav 2 mode


I'm not sure if this is really necessary for anything other than Samsung phones, but I've only ever seen this issue come up when dealing with Samsung phones. Here's a scenario: You're messing around with the various settings in your phone's menu, and you switch your phone to NAM2 in the process. Your phone resets, and you find that your phone is now locked. Unfortunately, your normal lock code doesn't work. What do you do?

First off, you should probably understand what NAM1 and NAM2 are. Basically, think of them as containers. Each of these "containers" holds a phone number. Yes, you can have two phone numbers on a single cell phone. I generally don't recommend it, though, as you can only have one of the two numbers active on the phone at any given time, meaning that you'll miss all of your calls on the number whose NAM you're not on at the moment. Also, NAM2 generally can't accept over-the-air programming, so you'll need to manually program your account information into it, and you'll need to have updated roaming information loaded into your phone in one of your carrier's retail stores (assuming that they even support NAM2).

So, why am I telling you about NAM1 and NAM2? Well, your default lock code (assuming that you never specified your own) is generally going to be the last four digits of your phone number. Problem is, NAM2 doesn't have a phone number in it by default, so you'll need to somehow figure out what the default lock code is set to on NAM2.

Secondly, you'll need to locate a hexadecimal code, usually found inside of your phone's battery compartment. There are two different types of hexadecimal codes that you'll need to be on the lookout for: ESN and MEID. Now, Samsung phones generally don't have these numbers labeled, but it's easy enough to find them. An ESN in HEX format will be eight characters long, whereas an MEID in HEX format will be fourteen characters long. MEID's tend to begin with the letter A from my experience.

Now, depending on which type of hexadecimal code you found in the previous step, you'll need to take one of two different paths in determining your unlock code...

Let's start with the easier path, the ESN...

Thankfully, all you need for this one is a scientific calculator. If you're using Windows, then simply launch Calculator. Once you've launched Calculator, you'll want to choose View > Scientific from the menu bar.



Once you're in scientific mode, click on the Hex radio button, then enter the eight-character ESN.



Now, click on the Dec radio button to convert your ESN into DEC format. Now, do bear in mind that this won't be the same as the ESN number in DEC format on your phone's battery compartment label. That's why only the ESN in HEX format is important. Anyway, the last four digits of the resulting number are what you'll want to enter in order to unlock your phone.



Now, let's move on to the slightly more involved path, the MEID...

Really, the only reason that I consider this to be harder than the previous path is because it requires a tool that isn't available on most computers by default. Basically, you'll need to find a hash calculator, specifically one that's capable of working with the SHA-1 algorithm. You don't really need to understand what the SHA-1 algorithm is in order to unlock your phone, but - in case you wanted to know, anyway - I suppose that it'd best be described as a method of making pieces of code more secure. SHA-1 and other similar algorithms simply make changes to code in order to make said code more secure.

Anyway, I'd recommend HashCalc, as it's free and easy-to-use. Once you've downloaded and installed HashCalc, launch it. Change the Data Format option to Hex String, then enter your fourteen-character MEID. Be sure to check the SHA1 checkbox, then click on Calculate. See that long code that appeared to the right of the SHA1 checkbox? Write down the last six characters of it, as they'll be vital in determining your lock code.



Now, this next part will look more than a little familiar. Basically, you'll want to have a scientific calculator for this, just as we did for the first path. Again, in Windows, you can simply launch Calculator and choose View > Scientific from the menu bar.



Once you're in scientific mode, click on the Hex radio button. There's a problem, though: We don't have an eight-character code to put in as we did before, and we need an eight-character code in order to figure out our lock code. Well, thankfully, the first two characters in the eight-character code are always going to be 80. As such, your eight-character code will be the number 80, followed by the six characters that you wrote down after using HashCalc. Now that you have an eight-character code, input that code into your calculator.



Now, click on the Dec radio button. As before, the last four digits of the resulting number is your lock code.

My razor cell keeps roming


Try dialing *228 to update your roaming preferences. It should connect to verizon's automated roaming update service.

Unfortunately, it won't normally update if you are not already on a Verizon tower. If *228 will not connect, also try *22804, which attempts to push it through to the nearest Verizon tower, or *22890.

If you do get through, it will give you a welcome message, and ask you to select option 1 to reprogram, or option 2 to update roaming preferences. You will need to select option 2.

If you do not get through, unfortunately you will have to stop by a Verizon Wireless Corporate owned store and speak with their tech department. They will be able to tell you if you have the latest PRL (preferred roaming list) and also check to see if you have the latest firmware (which could be part of the issue). They will have the tools to manually reprogram the roaming listing in the phone.
